Question

我刚刚开始使用D3。我看过教程，现在我正在尝试自己的教程。试图根据我的数据结构获得一些彩色div标签。什么都没发生，我需要一些帮助来解决这个问题：

HTML：

<div class="chart"></div>
<script src="https://d3js.org/d3.v3.min.js"  charset="utf-8"></script>

CSS：

.chart div {
        font: 10px sans-serif;
        background-color: white;
        text-align: right;
        padding: 3px;
        margin: 1px;
        color: gray;
        width: 15px;
        height: 15px;
    }

JavaScript的：

var threshold = 0.5
        var data = []
        data[0] = JSON.parse('{ "smiles": "CCCCC=O", "prediction": [ { "pValue": 0, "label": "bar" }, { "pValue": 0.7, "label": "foo" } ] }')
        data[1] = JSON.parse('{ "smiles": "CCCCC=O", "prediction": [ { "pValue": 0.3, "label": "bar" }, { "pValue": 0.6, "label": "foo" } ] }')
        data[2] = JSON.parse('{ "smiles": "CCCCC=O", "prediction": [ { "pValue": 0.4, "label": "bar" }, { "pValue": 0.4, "label": "foo" } ] }')
        data[3] = JSON.parse('{ "smiles": "CCCCC=O", "prediction": [ { "pValue": 0.5, "label": "bar" }, { "pValue": 0.3, "label": "foo" } ] }')
        data[4] = JSON.parse('{ "smiles": "CCCCC=O", "prediction": [ { "pValue": 0.6, "label": "bar" }, { "pValue": 0.2, "label": "foo" } ] }')

        d3.select(".chart")
            .selectAll("div")
              .data(data)
            .enter().append("div")
            .style("background-color", function(d) {

                if (d['prediction'][0]['pValue'] > threshold &&
                    d['prediction'][1]['pValue'] > threshold) {
                        "green"
                    }
                if (d['prediction'][0]['pValue'] > threshold ) {
                        "blue"
                }
                if (d['prediction'][1]['pValue'] > threshold ) {
                        "yellow"
                }
            })

在为div设置颜色的功能中，你没有任何回报。 Fiddle。我在你的if语句中添加了if (d['prediction'][0]['pValue'] > threshold && d['prediction'][1]['pValue'] > threshold) { return "green" } if (d['prediction'][0]['pValue'] > threshold ) { return "blue" } if (d['prediction'][1]['pValue'] > threshold ) { return "yellow" }，现在可以正常使用了！

# Perform the import of the custom tool
$project.DTE.ExecuteCommand("Tools.ImportandExportSettings", "/import:""$fileName""");

"--Remove file"
Remove-Item -path $fileName

似乎无法在D3.js中发生任何事情。我该如何调试？
